When Rahul walks up a stationary escalator,then he takes 20s to reach the top.While when he walks up a moving escalator,he takes 10s to reach the top.The time taken by him to reach the top when stand still on the moving escalator is?

A boy reaches the airport and finds that the escalator is not working. He walks up the stationary escalator in time t_(1) . If the remains stationary on a moving escalator then the escalator takes him up in time t_(2) . The time taken by him to walk up on the moving escalator will be :

A passenger is walking on an escalator at a speed of 6 km/h relative to the escalator. The escalator is moving at 3 km/h relative to ground and has a total length of 120 m. The time taken by him to reach the end of the escalator is

At a metro station, a girl walks up a stationary escalator in time t_1 If she remains stationary on the escalator, then the escalator take her up in time t_2 . The time taken by her to walk up the moving escalator will be.

What work should a man do to walk up a subway escalator moving down with speed v ? The height of the escalator is h , and the man walks up the escalator at a speed u.

A person walks up a stationary escalator in t_(1) second. If he remains stationary on the escalator. Then it can take him up in t_(2) swcond. If the length of the escalator is L , then a. Determine the speed of man with with respect to the escalator. b. Derermine the speed of the escalator. How much time would take him to walk up the moving escaltor?.

A 90-kg man runs up an escalator while it is not in operation in 10s . What is the average power developed by the man. Suppose the escalator is running so that the escalator steps move at a speed of 0.5m^-1 . What is then the power developed by the man as seen by the ground reference if he moves at the same speed relative to the escalator steps as he did when the escalator is not in operation?

Shyama and Vyom walk up an escalator (moving stairway). The escalator moves at a constant speed. Shyama takes three steps for every two of Vyom's steps. Shyama gets to the top of the escalator after having taken 25 steps, while Vyom (because his slower pace lets the escalator do a little more of the work) takes only 20 steps to reach the top. If the escalator were turned off, how many steps would they have to take to walk up?
